MagicDragon..this is a good point you brought up too..

what do humans, lions, sheeps, birds, trees, have in common? they all have two sexes....why all of us have two different sexes? is not this what is necessary to keep us going?

Adey,
I would like to ask you this: could arrays of different forms of life result in humans, and yet in other creations and go to the extent that all of them have two sexes? how would you view/explain this?
